however the central heating temperature setting is still on 70 or so

the heating is switched on?

just wondering whether its worth switching the boiler off when im
out? i do sometimes notice it starting up when im not using any water
and the heatings off.. wonder if im wasting any gas.

OMFG - the amount of thick people in newsgroups amazes me.
You are a real TROLL!

It seems a not unreasonable question. I have got a Glow-worm combi (24Cxi)
and the recommended 'economy' setting keeps the water in the heat
exchanger hot, which in turn means it fires up every 45 minutes or so
whether or not you are calling for heating or hot water. Fortunately you
can turn this behaviour off.
